Product instruction:

A screw, or bolt, is a type of fastener, typically made of metal, and characterized by a helical ridge,

known as a male thread (external thread) or just thread, wrapped around a cylinder. Some screw

threads are designed to mate with a complementary thread, known as a female thread (internal thread),

often in the form of a nut or an object that has the internal thread formed into it. Other screw

threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common

uses of screws are to hold objects together and to position objects.A screw will almost always have a

head on one end which contains a specially formed shape that allows it to be turned, or driven, with a

tool. Common tools for driving screws include screwdrivers and wrenches. The head is usually larger

than the body of the screw, which keeps the screw from being driven deeper than the length of the

screw and to provide a bearing surface. There are exceptions; for instance, carriage bolts have a

domed head that is not designed to be driven; set screws often have a head smaller than the outer

diameter of the screw; J-bolts have a J-shaped head which is not designed to be driven, but rather is

usually sunk into concrete allowing it to be used as an anchor bolt. The cylindrical portion of the screw

from the underside of the head to the tip is known as the shank; it may be fully threaded or partially

threaded.
